摘　　要：介绍了磁绝缘传输线的阻抗大小、传输电压及电流大小对其产生的空间电子流大小及阴极电子鞘层厚度的影响。运用CHIPIC软件建立四层圆盘锥形磁绝缘传输线A层的近似化三维模型进行模拟,对比理论计算值与模拟值,并与相关文献的二维模拟结果进行对照,验证三维模拟的正确性。最后,模拟研究了圆盘锥形磁绝缘传输线阴阳极之间的间距变化对传输效率的影响。This paper investigates the effects of the impedance, and transmission voltage and current of magnetically insulated transmission lines（MITLs） on the current of the generated space electron flow and the thickness of the cathode electron sheath. The three-dimensional approximate model of the four-layer disc cone MITLs is established and simulated by CHIPIC software. The comparison of the theoretical calculation, the three-dimensional simulation values and the two-dimensional simulation results of some relevant literatures verifies the correctness of the three-dimensional simulation. Finally, the effects of the distance changes between anode and cathode on transmission efficiency of the disc cone MITLs are studied.
